Hi Burr, also -

> Even in the curved surface example you show though, I was looking for some type of "uniform coverage" method...

If you wanted something that was a bunch of curves uniform in UV space but then created as 3D isocurves you could do that using Flow - set up a plane with a pattern of lines on the plane however you want them arranged in UV space and then use Flow to map them from that plane onto the curved surface.

Flow can work with a batch of lines so it might be better suited for what you are thinking about.
